VTASHING- Application filed September 10, 1919.

To all to 7mm 2'2, may concern Be it known that I, Piiono Oninnnin, 21 subject of Italy, residing at Schenectady, in the county of Schenectady and idtate of New York, have invented new and useful linprovernents in ashing-Mschines, 01 which the following is it specification.

Reference may be had to the accompany ing drawings, and the reference characters marked thereon, which form a port of this specification. Similar characters refer to similar parts in the several figures therein.

This invention relates to a. type of clotheswnshing-niuchine having an oscillating dasher, with clamping mechanism for detucheloiy mounting clothes thereupon whereby the clothes are repeatedly dashed into the wash-water or suds in the operation oi the machine.

The principal object of my invention is to automatically cause :i more effective movement of the dusher of which its simple oscillating movement is it component.

Other objects will appear in connection with the following description.

invention is shown in preferred form, 1 is a tub supported by legs, 2, mounted upon casters, 2, the tub being of elongated fornil i he top-plate, 3, extends across the middle portion of the tub, leaving openings, 4:, along each side of the board for access to the interior oi the tub.

These openings, 4-, are adapted to be closed by lids or doors, 5, hinged at 6 upon the tub and adapted to he swung down alongside the tub when desired, as shown at the lefthsnd side of Fig. 1.

Ti lie bottom of the tub is preferably corrugated as shown at 7.

clothes are carried by it dasher comprising a frame, 8, carrying a roller, 9, and (TlllllP-ljtll', 1U, ndjustebly mounted upon the frame, 8, uuierehy the clothes can be clamped between the roller, 9, and the clamp-bar, 10.

'lhe side members of the frame, 8, have along their inner sides teeth, 11, adopted to be engaged by a pair of dogs, 12, slidably mounted upon the clamp-bar and adapted to he forced into and out of engagement with the teeth, 11, by means 01 a hand-operated crank-(ii... c, 13, carrying crank-pins, 14, engngcnble respectively with ofiset portions, 15, on the respective dogs, 12.

The dssher is carried by a slide, 16, reciproceble in u slideway, 17, which extends longitudinully of a rocker, 18, rockably mounted at 19, upon :1 bracket, 20, depending from the top-plate, 3, whereby oscillating movemerits of the slide 16, longitudinally of the tub are permitted.

The slide, 16, is provided with a longitudinal slot, 21, forming a sildeway for a crank-pin beoringbox, 22, which forms a bearing for z. crsnlepin, 23, carried by a crank-arm, 24, fixed upon o. shaft, 25, rotntively mounted in bearings, in uprights, 26, erected from the top-plate,

The sha it, 25, is connected by gears, 2?, with e. counter-shaft, 28, also rotatively mounted in hearings in said uprights, 26.

The shaft, 'insy be operated by power or hand in any known manner.

I have shown a hand-wheel, 29, fixed upon illCl shaft, 28, whereby the some may be operated.

The crank-pin bearing-box, 22, is provided with a pair of slidewoy apertures, 30, for a pair of dogs, 31, which dogs in a certain position of said bearing-box relatively to the slide, 16, are adapted to enter and engage openings, 32, in said'slide whereby the slide and the crank-pin bearing-box are locked in fixed relation to each other, and when so locked together the slide will partake of the movement ofthe crank-pin bearing-box to ward and from the axis of oscillation of the rocker, 18, so that a longitudinal reciprocating movement will be imparted to the slide anddasher relatively to the rocker, 18, while the rocker and the slide with the dasher are oscillated by the continuous move-- ment of the crank 24.

When the dogs, 31, are withdrawn from the openings, 32, in the slide, the slide is left free from the bearing-box permitting the bearing-box to reciprocate along the slidewayslot, 21, in the slide as the crank is continuously operated, without longitudinal movement of the slide relatively to the rocker, 18.

F or certain purposes of the invention, the dogs, 31, may be forced into the respective openings, 32, in the slide and withdrawn therefrom in any known manner.

I haveshown a preferred form of mecha nism whereby this result is accomplished automatically in the operation of the machine, which mechanism is shown in detail in Figs. 2, 3 and 5.

In this construction the dogs, 31, are forced inwardly and outwardly by means of a lever, 33, fulcrumed at 34, upon a l racket, 35, extending upwardly from the crank-pin bearing-box, 22, the lower end of said lever having fork-members, 36, which respectively engage recesses or openings, 37, in the respective dogs, 31.

The upper end, 38, of said lever, 33, is in the path of a cam, 39, on a cam-wheel, 40, rotatively mounted upon a spindle, 41, projecting laterally from the bracket,

A coil-spring, 42, interposed between the bracket, 35, and the upper end of the lever,

33, tends to hold the upper end of the lever against the cam, 39, and to force the dogs, 31, inwardly into the openings, 32, in the slide when the lever is released from the in fluence of the cam, 39, and thebearing-box is in the slide.

A portion of the inner face of the cum- 7 Wheel, 40, is cut-away at 43, to permit the lever, 33, to be thus actuated by the spring, 42, at certain times. At certain other times when the upper end of the lever, '33, is en gaged and forced inwardly by the cam, 39, against the force of the spring, 42, the dogs, 31, are withdrawn and heldwithdrawn from the respective openings, 32, in the slide.

The cam-wheel, 40, is automatically rotated by a step-by-step movement in the operation of the machine by engagement ofa dog, 44, with ratchet-teeth, 45, on the came proper position relatively to said wheel, said dog being mounted upon the rocker, 18, in position to said ratchetteeth during the latter part of each move ment of the crank-pin bearing-box toward the axis of oscillation of the rocker.

A hand-actuated dog, 46, is mounted upon the top-plate, 3, in position to be forced into and out of engagement with the gear-wheel, 27, on the shaft, 28, whereby when desired said gear maybe locked against rotative movement with the dasher held in any de sired position for convenience in inserting and removing the clothes.

The operation of the machine is as follows:

The operating members of the machine are locked against movement by a dog, 46, with the dashe' in convenient position for inserting the clothes which position is preferably adjacent to one of the openings, 4.

The dogs, 12, on the clamp-liar, 10, are withdrawn by operation of the crank-dis t. 13, permitting the clamp-bar to be separated from the roller, 9, to permit the clothes to be freely inserted between the roller and the clamp-bar.

The clamp-bar is then forced toward the roller, 9, to clamp the inserted clothes against the roller, in which position the clamp-bar is secured by forcing the dogs, 12, outward into engagement with the teeth, 11, on the dasher-frame by reverse movement of the crank-disk, 13.

The tub having been supplied with water or suds, the doors, 5,are closed and the shaft, 28, is rotated by means of the hand-wheel, 29, to impart a continuous movement to the crank, 24, and a step-by-step movement to the cam-Wheel, 40.

So long as the cam, 39, on the cam-wheel, 40, holds the upper end of the lever, 33, in innermost position the lower fork-endof said lever will hold the dogs, 31, disengaged from the openings, 32, in the slide; and as the crank is continuously operated its bearing-box will slide freely inwardly and outwardly along the slideway slot, 21, in the slide without imparting a longitudinalslidemovement to the slide.

When thus operated the slide remains in substantially fixed relation to the rocker, 18, and a simple oscillating movement is parted to the dasher longitudinally of the tub.

As the operation of the machine continues the step-by-step movement of the camwheel, 40, causes its cutaway portion, 43, to be brought opposite the upper end of lever, 33, releasing said lever to the action of the coil-spring, 42, tending to force the lower forkend of said lever inward and the dogs, 31, to enter the openings, 32, in the slide when the dogs are brought by the movement of the bearing box opposite said respective openings. The continued operation of the machine then causes the slide, 16, which is in fixed relation to the bearingbox to partake of the movement of the bearing box toward and from the axis of oscillation of the rocker, 18, thereby imparting to the slide, 16, a longitudinal reciprocating slidemovement relatively to the rocker, 18, whereby the dasher and clothes carried thereby are reciprocatingly moved toward and from the axis of oscillation of the rocker, While also being oscillated longitudinally of the tub.

The slide-movement thus imparted to the slide, 16, is indicated by dotted lines in Fig. 1.

In Fig. 2 the cam-wheel, 40, and lever, 33, are shown in position to hold the dogs, 31, withdrawn from the openings, 32, in the slide.

In Fig. 5 the lever, 33, is shown released from the control of the cam-wheel, 4:0, with the dogs, 81, held by the lever in engage ment with the openings, 32, in the slide.

In the continued operation of the machine, the dasher and clothes carried thereby can thus for a predetermined number of oscilla tions of the dasher be given a simple oscillating movement longitudinally of the tub, and for a certain number of oscillations of the dasher can be given a more complex movement, the resultant of the simple oscil lating movement of the dasher and the longitudinal reciprocating movement of the slide, 16.

I have shown the cam-wheel, 10, provided with twelve ratchet-teeth, 15, and with its cam-portion cut-away at 43, opposite four of said teeth. By this arrangement, in the continued operation of the machine the dasher will be given eight simple oscilla tions, then four oscillations accompanied by longitudinal movement of the slide, 16, then eight simple oscillations and so on indefinitely.

Any desired relative number of simple oscillations of the dasher can be obtained by providing the cam-wheel, 40, with more or less ratchet-teeth, and by extending the cut-away portion, 43, of the cam to a greater or less extent.

For certain purposes of the invention, the dasher may be of any known form.

A coil-spring, 47, confined under 00: pression between the cam-wheel, 40, and the bracket, 35, frictionally holds the cam-wheel from accidental movement while the cutaway portion, 43, of the cam is opposite the upper end of lever,
